Do your window screens look like they've been through a gunfight, and you haven't got money or time to replace them? Well, don't despair. To repair holes in aluminum screens, cut a patch slightly larger than the hole. Pull off one strand of wire on each side and bend remaining edge wires downward. Place the patch over the hole with bent-wire ends sticking through, and crimp them over on the backside to hold it. For fiberglass screens, cut a slightly larger patch and place it over the hole, matching the pattern. Add a thin bead of epoxy cement or super glue, even clear caulk will do, and dab off any excess before it dries. You can glue aluminum screening, too. It's a process of trial and error. And that's the On The House tip for today.
